On the back of a weekend of thrilling finals football where complaints were made about everything from referees to where they actually play the games, no one has been spared.

The cheerleaders are now under fire after Manly boss Scott Penn questioned why Penrith's Pantherettes were allowed to perform at the Sea Eagles' "home game" on Saturday at Allianz Stadium.

After the Panthers beat his Sea Eagles 22-10, Penn went on a rant about why his club should have been allowed to play at Lottoland, then bizarrely took aim at the rival cheerleaders, asking "why were they there if it's our home final?".

Panthers CEO Brian Fletcher came in to defended the Pantherettes, declaring: "He's drawing a long bow if he's complaining about our cheerleaders.

"As for playing at Allianz Stadium, we finished in front of Canterbury last year and had to play them there in week one, not Pepper Stadium.

"It's not like these rules happened overnight.

"It's just his club haven't played finals football in that long. His team went off a week early."

Laura Harrison, who runs the Pantherettes, said the squad had performed at several finals in recent years.

The NRL also confirmed it was in charge of all finals games - not the home teams - and cheerleaders from both clubs were allowed to participate.

"The NRL run it, they invited us, and we were more than happy to do it," Harrison said.

"We've been involved in finals games over the years. Last year (week one) was in Sydney, and we were there and the Bulldogs cheer squad was there."
